Does MongoDB use sharding?

Sharding is a method for distributing data across multiple machines. MongoDB uses sharding to support deployments with very large data sets and high throughput operations. Database systems with large data sets or high throughput applications can challenge the capacity of a single server.

When should you shard MongoDB?

Sharding is the most complex architecture you can deploy using MongoDB, and there are two main approaches as to when to shard or not. The first is to configure the cluster as soon as possible – when you predict high throughput and fast data growth.

Does MongoDB Sharding improve performance?

Sharded clusters in MongoDB are another way to potentially improve performance. Like replication, sharding is a way to distribute large data sets across multiple servers. Using what’s called a shard key, developers can copy pieces of data (or “shards”) across multiple servers.

Why do we need sharding?

Sharding is a method for distributing a single dataset across multiple databases, which can then be stored on multiple machines. This allows for larger datasets to be split in smaller chunks and stored in multiple data nodes, increasing the total storage capacity of the system.

What is sharding good for?

When should you shard your database?

Why would you shard a database?

Sharding is necessary if a dataset is too large to be stored in a single database. Moreover, many sharding strategies allow additional machines to be added. Sharding allows a database cluster to scale along with its data and traffic growth. Sharding is also referred as horizontal partitioning.

Can NoSQL be Sharded?

Sharding is a partitioning pattern for the NoSQL age. It’s a partitioning pattern that places each partition in potentially separate servers—potentially all over the world. This scale out works well for supporting people all over the world accessing different parts of the data set with performance.
